I heard people tank about a World of Infantry, but I would like it to stick with world of tanks. Here I have a tech tree, and I will explain what the infantry can do, and how the tanks can adapt.

General Infantry Game Mechanics:Infantry works differently. One controls only a single tank. For infantry, you control a whole platoon. You view the map in battle as if it was a Real Time Strategy game (or like in Spore Creature Stage where the other men follow your avatar. You can tell me how you like it to be.) The battle starts, and you click anywhere on the field you want your men to go. You can even divide your group to different location. Your platoon (of about 20 men) will be highlighted in any colour of choice so you don't confuse your me with another person's. After positioning your men, you can change to attack mode. You meerly click on the tank (or enemy platoon) you want to attack, and the men do the rest. No need to aim. In fact, you can chose to fight in full attack mode, or in cautious attack mode. Full Attack mode allows your men to open fire and dish out as much damage as they can. Cautious attack mode allows your men to deal as much damage as they can while still avoiding enemy fire and looking out for hidden tanks.

Tech Tree and Equipment Mechanics Here is the tech tree:

This is just in general, but you get the picture (literally!). Now, the upgrades work out like a single tank's upgrade tree rather than the tank tree with several different tanks. You research a tool and you can give it to your men. The game can automatically divide the different tools with the men if you want equal power. Otherwise, you can manually specialize your men to a certain skill, like anti-tank or anti-infantry. You can also equip your team with transport. Its dreadful enough driving slowly, never mind running. NOW, noticing the first vehicle is tier IV, it can be irritating to fight in a tier VI battle with no ride. That's why men can ride on tanks! WEEE!!! During a battle, you can hop aboard a tank to get to where you need to go, understanding that it's another player who's dictating your destination. Now, for you tankers, any infantry hopping on your tank will not affect the performance of your tank in any way. It will be like your tank having hair, it won't be a bother. In fact, men riding on your tank INCREASES your overall self defense. A tank destroyer is deadly if it has a bazookateer riding on the back and aiming behind it. If you buy grenades (which will require no research), you can hop onto an ENEMY tank and plop a grenade in the hatch if you have not unlocked any antitank weaponry.

Tank Adaptations Now, you tankers, you probably wet yourselves after reading,"a tank destroyer is deadly if it has a bazookateer riding on the back and aiming behind it." But don't worry. Tanks will get their share of upgrades to defend themselves against soldiers. Tanks will be fitted with a machine gun & you can research a flamethrower as well. Enemy tanks with soldiers crawling all over them can be easily hosed by a friendly machine gun to get rid of those pests without having a hole blown through your hull.

New Game Play for Light Tanks in High Tier Battles Light tanks were made to support and kill infantry. Infantry can be an even more dangerous for high tiered heavies than even artillery can because infantry can come out of nowhere in shear numbers!!! THIS is when light tanks can help. If a group of heavies is being held up by 1-2 platoons (very dangerous if properly armed!), a light tank can rush behind them and hose them with a machine gun. Light tanks can also supply fast, easy, and free transport for soldiers. Speed also keeps enemy soldiers form climbing onto your tank to grenadify you! No more suicide scouting! YAY!!!!!

If you have any questions, or if you would like me to add more, just state your idea, and I will post it as soon as possible!

I actually thought of having infantry on the maps as a sort of "dynamic scenery". Them fighting it out with each other, without having any effect on the tanks. Purely to make the game more lively and battle-like. But that entails much technical issues, plus would bump up the age rating.
So.. eh.

no, don't like the diea, it would completely ruin the game.
if you want to have infantry and tanks go play BF*, wot right now is spiffy and bullshitish enough as it is without adding BS infantry shooting molotovs at your T10 tank and killing it...
noone wants their T9/10 tank ruined by some dork with a bazooka hiding in a bush completely undetected.

so no matter how good the idea/theory you put, infantry has no place in WoT

I think they should add crew members that are visible in the open topped tanks and have option of putting your commander in the cupola and have him actually increase your detection. either way they said infantry is going to come, hopefully just as spotters or ai in the pill boxes. Driving arty around or open topped tanks gives a maximum overdrive machines come alive type of feel instead of true WWII thats just imo

they actually said "infantry IS NOT going to come", it's in one of the interviews with WG CEO.
they're not gonna add visible crewmembers for the time being(which means like 2 years in real life for wot) as the game needs a huge ton of optimization(multicore computing, hello?) before that

I think it would be a good idea at some point but before that happens better game engine retooling needs to be done and at some point WoWP and WoBS will be out and the devs plan on turning all three into one game (hopefully as an option)so infantry would just complete the full WW II battlefield experience at that point.
Edit: would be like a non retarded battlefield europe which has going on 15-20 year old game engine and graphics and the high command structure would be missing as well.

Do not want to see infantry trying to destroy my tank! After playing Men of War, I am scared of AT grenades as one of them can disable almost any tank and AT grenades don't have fuses, they are impact grenades.

For the mini gun naysayers the "heavy" (non mini) would actually come first for the Western powers and be in period as the Vulcan 20mm was designed in 1946. Problem being it was developed for aircraft use. The actual mini 7.62x51 wasn't developed until 1962, out of period. The Russians would have one in both mini and non mini with the Slostin 7.62x54 and 14.5x114 guns, just post WWII. Either way, there is as much "support" for their inclusion as there is for many of the tanks already in game.

But... World of TANKS

Maybe some year we will see a combined arms game along these lines from Wargaming, but for now tanks should fight tanks.
